How many maps have we seen from them and you're already calling them a bad / low tier team?
Stop defending Renegades and make it seem like they're som top tier team, their only decent LAN showing in recent times was losing to mousesports in an IEM sydney quarterfinal. Other than that they've failed to perform under pressure in most LAN tournaments.
I'm not saying Renegades are a bad team, but you hinting at Optic being crap while at the same time always defending Renegades and seem to believe they're some top tier team is kinda hypocritical.

I'm not calling Optic bad, They are around the same level as Renegades, So Renegades beating Optic isn't an achievement, Some would say Renegades are favorites some wouldn't,
You do know Renegades beat FaZe in an even better game to actually make the playoffs right? And that got them to face Mouz ... And not calling Renegades top tier, They probably could though, They have been like 1 roster move away for so long.
Stop presuming things, You're often wrong

You made it seem (hinting at) like Optic being bad is a fact.
I do know they beat Faze, and I said that tournament was an impressive showing from them.
And about the last part, if I'm so often wrong, how do I make a lot of money betting? Kinda interesting. You on the other hand, always talk about ''Renegades are 1 roster move from this or that''. Well, with all the roster moves that have been made, one thing has stayed with them, the ability to perform under pressure has rarely been with them.

What's wrong with betting in 2018? I bet with real money, not skins, and I make good money.
So Renegades are better on LAN than online huh? Just watch their matchups versus C9 or Liquid, the top teams in NA statistically and on paper. The only times they've beaten these teams are online. They've never (expect for once in a BO1 versus C9) beaten these guys on LAN and I'm going a year back in time. They've beaten Liquid in online quals and Pro league etc, but never once the LAN pressure has been applied. If I remember correctly it's the same case with the SK matchup.
It's a known thing, casters and analysts have highlighted it many many times before, that Renegades do struggle when the pressure is applied. Just look at how they went out to Avangar in the Major qual, a team they should beat every day of the week.

Real money is fine i guess, Skin betting now just horrible compared to the csgo lounge days,
Before saying they haven't beat Liquid on LAN in over a year for say, Say how much they have actually played on LAN the past year, Because they have only played 3 times the last year (Renegades have won 1 map, Liquid has won 4, Just the 1 overtime) Yes Liquid is better but they were all close,
We could compare Renegades with the old EU Optic for example, They played 2 games on LAN, 3 maps on LAN, Renegades all times beat them,
Think going into that major they already knew NAF was leaving, They really ... really should have made it out of groups

Either way, I don't think Renegades are particularly better on LAN than online. Their results say that they can play really well both online and on LAN, but also are having trouble in high pressure games, on LAN.
Saying that, I'll go with Renegades winning this one. Pure value bet, 2.6 odds and I haven't seen enough from Optic to know what to expect, but I roughly know Renegades will perform.
They could do extremely well if they wouldn't feel so pressured all the time, and I feel like the AU players are most affected by this compared to Nifty / Jkaem.
